Hello! I have the same problem on my Lenovo Thinkpad T490s (20NXCTO1WW) with a Fibocom L830-EB LTE WWAN Modem device after upgrade to Fedora 37.
Can you try this copr and let me know if it fixes the issue? https://copr.fedorainfracloud.org/coprs/dcavalca/ModemManager/
Hi! I have updated the following packages from the copr repository and now the ModemManager did not crash anymore. The modem connection appears the gnome menue and works fine. ModemManager-1.20.2-1.fc37.x86_64 ModemManager-glib-1.20.2-1.fc37.x86_64 libmbim-1.28.2-1.fc37.x86_64 libmbim-utils-1.28.2-1.fc37.x86_64 libqmi-1.32.2-1.fc37.x86_64 libqmi-utils-1.32.2-1.fc37.x86_64 Thank you very much for your engagement. Regards, Franz
I am currently using Fedora Linux 37 Silverblue, so using DNF in a toolbox will not work for system level upgrades. Even if I download the RPM's and install using 'rpm-ostree override replace *.rpm' those packages will not be upgraded going forward. James
I will override the current packages just to check if it works on my end, and report back, then uninstall them to preserve system integrity.
It works! Great job. Hopefully they can push this to the maintainer soon. Until then, I'll leave these packages in place and revert back when they are in the Fedora repository. Now I don't have to boot into another OS to get to my GitHub. Thanks again, James
This package has changed maintainer in Fedora. Reassigning to the new maintainer of this component.
